Method and System for Providing Integrated Analyte Monitoring and Infusion System Therapy Management

ABSTRACT

Method and system for providing diabetes management and insulin therapy based on substantially real time glucose monitoring system is provided.

BACKGROUND

With increasing use of pump therapy for Type 1 diabetic patients, youngand old alike, the importance of controlling the infusion device such asexternal infusion pumps is evident. Indeed, presently available externalinfusion devices typically include an input mechanism such as buttonsthrough which the patient may program and control the infusion device.Such infusion devices also typically include a user interface such as adisplay which is configured to display information relevant to thepatient's infusion progress, status of the various components of theinfusion device, as well as other programmable information such aspatient specific basal profiles.

The external infusion devices are typically connected to an infusion setwhich includes a cannula that is placed transcutaneously through theskin of the patient to infuse a select dosage of insulin based on theinfusion device's programmed basal rates or any other infusion rates asprescribed by the patient's doctor. Generally, the patient is able tocontrol the pump to administer additional doses of insulin during thecourse of wearing and operating the infusion device such as for,administering a carbohydrate bolus prior to a meal. Certain infusiondevices include food database that has associated therewith, an amountof carbohydrate, so that the patient may better estimate the level ofinsulin dosage needed for, for example, calculating a bolus amount.

However, in general, most estimation or calculation of a bolus amountfor administration, or a determination of a suitable basal profile, forthat matter, are educated estimates based on the patient's physiology asdetermined by the patient's doctor, or an estimate performed by thepatient. Moreover, the infusion devices do not generally includeenhancement features that would better assist the diabetic patients tocontrol and/or manage the glucose levels.

In view of the foregoing, it would be desirable to have a method andsystem for providing insulin therapy determination and recommendationbase on real time monitored analyte levels of the patient for proactiveinsulin therapy treatment to improve management of diabetes.

FIG. 3 is a flow chart illustrating insulin therapy management procedurebased on real time monitored analyte levels in accordance with oneembodiment of the present invention. Referring to FIG. 3, in oneembodiment of the present invention, a predetermined number ofconsecutive glucose levels are received or detected over a predeterminedor defined time period. For example, in one embodiment, referring toFIG. 1, the monitored glucose levels of a patient is substantiallycontinuously received or detected substantially in real time for apredetermined time period. In one embodiment, the predefined time periodmay include one or more time periods, the data within which may providea therapeutically meaningful basis for associated data analysis.

That is, the predefined time period of the real time monitored glucosedata in one embodiment may include one or more time periods sufficientto provide glucose trend information or sufficient to provide analysisof glucose levels to adjust insulin therapy on an on-going, andsubstantially real time basis. For example, the predefined time periodin one embodiment may include one or more of a 30 minute time period, a30 minute time period, a 45 minute time period, a one hour time period,a two hour time period and a 6 hour time period. While exemplarypredefined time periods are provided herein, within the scope of thepresent invention, any suitable predefined time period may be employedas may be sufficient to be used for glucose trend determination and/ortherapy related determinations (such as, for example, modification ofexisting basal profiles, calculation of temporary basal profile, ordetermination of a bolus amount).

Referring back to FIG. 3, the consecutive glucose levels received overthe predefined time period in one embodiment may not be entirelyconsecutive due to, for example, data transmission errors and/or one ormore of potential failure modes associated with data transmission orprocessing. As such, in one embodiment of the present invention, thereis provided a predetermined margin of error for the received real timeglucose data such that, a given number of data points associated withglucose levels which are erroneous or alternatively, not received fromthe glucose sensor, may be ignored or discarded.

Referring back to FIG. 3, upon receiving the predetermined number ofglucose levels over a predefined time period, the glucose trendinformation based on the received glucose levels is updated. Forexample, in one embodiment, the glucose trend information estimating therate of change of the glucose levels may be determined, and based uponwhich the projecting the level of glucose may be calculated. Indeed, inone embodiment, the glucose trend information may be configured toprovide extrapolated glucose level information associated with theglucose level movement based on the real time glucose data received fromthe glucose sensor. That is, in one embodiment, the real time glucoselevels monitored are used to determine the rate at which the glucoselevels is either increasing or decreasing (or remaining substantiallystable at a given level). Based on such information and over apredetermined time period, a glucose projected information may bedetermined.

Referring again to FIG. 3, the therapy related parameters associatedwith the monitored real time glucose levels is updated. That is, in oneembodiment, one or more insulin therapy related parameters of an insulinpump such as including, but not limited to, insulin on board informationassociated with the fluid delivery device 120 (FIG. 1), insulinsensitivity level of the patient 130 (FIG. 1), insulin to carbohydrateratio, and insulin absorption rate. Thereafter, in one embodiment, oneor more modifications to the current therapy profile are determined.That is, in one embodiment of the present invention, one or more currentbasal profiles, calculated bolus levels, temporary basal profiles,and/or any other suitable pre-programmed insulin delivery profilesstored in the fluid delivery device 120 (FIG. 1) for example, areretrieved and analyzed based on one or more of the received real timeglucose levels, the updated glucose trend information, and the updatedtherapy related parameters.

Referring back to FIG. 3, after determining one or more modifications tothe therapy profiles, the modified one or more therapy profiles isgenerated and output to the patient 130 (FIG. 1) so that the patient 130may select, store and/or ignore the one or more modified therapyprofiles based on one or more of the monitored real time glucose values,updated glucose trend information, and updated therapy relatedparameters.

For example, in one embodiment, the patient 130 may be provided with arecommended temporary basal profile based on the monitored real timeglucose levels over a predetermined time period as well as the currentbasal profile which is executed by the fluid delivery device 120(FIG. 1) to deliver a predetermined level of insulin to the patient 130(FIG. 1). Alternatively, the patient 130 in a further embodiment may beprovided with one or more additional recommended actions for selectionas the patient sees suitable to enhance the insulin therapy based on thereal time monitored glucose levels. For example, the patient may beprovided with a recommended correction bolus level based on the realtime monitored glucose levels and the current basal profile inconjunction with, for example, the patient's insulin sensitivity and/orinsulin on board information.

In this manner, in one embodiment of the present invention, based onreal time monitored glucose levels, the patient may be provided with anon-going, real time insulin therapy options and modifications to thepre-programmed insulin delivery basal profiles so as to improve upon theinitially programmed therapy profiles based on the monitored real timeglucose data.

FIG. 4 is a flowchart illustrating analyte trend information updatingprocedure based on real time monitored analyte levels in accordance withone embodiment of the present invention. Referring to FIG. 4, in oneembodiment, real time data associated with monitored analyte levels isreceived. Thereafter it is determined whether the real time data hasbeen received for a predetermined time period. If it is determined thatthe real time data has not been received for at least the predeterminedtime period, then the routine continues to receive the real time dataassociated with the monitored analyte levels such as glucose levels.

On the other hand, referring back to FIG. 4, if it is determined thatthe real time data associated with the monitored analyte levels has beenreceived for the predetermined time period (for example, as describedabove in conjunction with FIG. 3), then, the received real time dataassociated with the monitored analyte levels is stored. Thereafter,analyte level trend information is determined based on the received realtime data associated with the monitored analyte levels.

For example, in one embodiment, the real time data associated with themonitored analyte levels is analyzed and an extrapolation of the databased on the rate of change of the monitored analyte levels isdetermined. That is, the real time data associated with the monitoredanalyte levels is used to determined the rate at which the monitoredanalyte level changed over the predetermined time period, andaccordingly, a trend information is determined based on, for example,the determined rate at which the monitored analyte level changed overthe predetermined time period.

In a further embodiment, the trend information based on the real timedata associated with the monitored analyte levels may be dynamicallymodified and continuously updated based on the received real time dataassociated with the monitored analyte levels for one or morepredetermined time periods. As such, in one embodiment, the trendinformation may be configured to dynamically change and be updatedcontinuously based on the received real time data associated with themonitored analyte levels.

FIG. 5 is a flowchart illustrating modified therapy management procedurebased on real time monitored analyte levels in accordance with oneembodiment of the present invention. Referring to FIG. 5, in oneembodiment, the current therapy parameters are retrieved and, theretrieved current therapy parameters are analyzed based on the receivedreal time data associated with the monitored analyte levels and/orupdated analyte trend information. For example, one or morepreprogrammed basal profiles, correction bolus, carbohydrate bolus,temporary basal and associated parameters are retrieved and analyzedbased on, for example, the received real time data associated with themonitored analyte levels and/or updated analyte trend information, andfurther, factoring in the insulin sensitivity of the patient as well asinsulin on board information.

Referring to FIG. 5, based upon the analysis of the current therapyparameters, one or more modified therapy profiles are calculated. Thatis, based upon the real time glucose levels monitored by the analytemonitoring system 110 (FIG. 1), a modification or adjustment to thepre-programmed basal profiles of the fluid delivery device 120 (FIG. 1)may be determined, and the modified therapy profiles is output to thepatient 130 (FIG. 1). That is, the modification or adjustment to thepre-programmed basal profiles may be provided to the patient for reviewand/or execution to implement the recommended modification or adjustmentto the pre-programmed basal profiles.

In this manner, the patient may provided with one or more adjustments tothe existing or current basal profiles or any other pre-programmedtherapy profiles based on continuously monitored physiological levels ofthe patient such as analyte levels of the patient. Indeed, in oneembodiment of the present invention, using continuously monitoredglucose levels of the patient, modification or adjustment to thepre-programmed basal profiles may be calculated and provided to thepatient for review and implementation as desired by the patient. In thismanner, for example, a diabetic patient may improve the insulin therapymanagement and control.

Within the scope of the present invention, the processes and routinesdescribed in conjunction with FIGS. 3-5 may be performed by the analytemonitoring system 110 (FIG. 1) and/or the fluid delivery device 120(FIG. 1). Furthermore, the output of information associated with themodified therapy parameters, trend information, and/or real time dataassociated with the monitored analyte levels may be displayed on adisplay unit of the receiver of the analyte monitoring system 110 (FIG.1), or the infusion device display of the fluid delivery device 120(FIG. 1) or both. Alternatively, one or more such information may beoutput to the patient audibly as sound signal output.

In this manner, in accordance with the various embodiments of thepresent invention, there are provided methods and system for providinginformation associated with the direction and rate of change of analyte(e.g., glucose) levels changes for determination of, for example, bolusor basal rate change recommendations, for comparing expected glucoselevel changes to actual real time glucose level changes to update, forexample, insulin sensitivity factor in an ongoing basis, and forautomatically confirming the monitored glucose values within a presettime period (e.g., 30 minutes) after insulin therapy initiation todetermine whether the initiated therapy is having the intendedtherapeutic effect.
